deleteData
Canonical ID: storage.delete. Nederlands: verwijderGegeven.
Removes one app-private key and returns true only if that key existed. Deleting a missing key returns false and is harmless. The key is still validated even when absent. This operation removes saved data, not a project asset or a host file.
Signature
deleteData(key)
Arguments
| Parameter | Type | Requirement |

Return value
Boolean.
Example
# language: en
saveData("temporary", 12)
say deleteData("temporary")
say deleteData("temporary")
Prints true then false.
Notes and common mistakes
Use the function name for your source language. Its canonical ID is a shared documentation label; you do not type that ID as a call. Giving your own variable or function the same name can hide the built-in. Supply the documented arguments and value types. Pliro reports mismatches when checking can detect them, or when the call runs.
Keys and saved text are not translated. Limits are 128 keys, 64 KiB per JSON value, 512 KiB per document, 32 nesting levels, and 8,192 values/nodes per value. Functions, nonfinite numbers, and Maps with non-Text keys cannot be stored. A usable portable project identity enables durable data; loose source uses temporary session storage. See the storage guide for E4014–E4017 and copy/identity rules.
